Inventor x and at its opposite end is provided with a cam roll 48 which bears against the cam 30. A spring 491 is fastened at. one end to the lever 46 and at the other end to the frame and acts to hold the roll l8 in en gagenlent with the cam during its operation. s

The rivets are'transferred fronrthe raceway 32 to the raceway 34 one at a time by the slide 33 which is operated by a lever 50 pivoted at 51 to the frame of the machine. and has a rocking movement imparted thereto in one direction by a spring 52 and in the opposite direction by a projection 53 on the rear side of the link 25. Theoperation of the slide in transferring the rivets from the raceway 32 to the raceway 34 is well known to those skilled in the art and, as it forms nopart of this invention, requires no further description.

Astationaryworlsupport 54 is fastened to an arm 55 forming a portion of the frame 10 and said work-support terminates at its outer end in a sleeve 56 which surrounds an anvil 57=formed upon the upper end of a tube 58 which is slida-bly mounted in the outer endof the armf'55r Within said tube is inclos'ed a spring 59 the' lower end of which bears against an adjusting screw 60,

"and the upper end of which bears against a collar 61 fast to a guide pin 62 which' projects'upwardly through the anvil and normally beyond the upper surface 63 of the .work-support 54. The lower end of the tube 58 has cars 64 to which a toggle link 65 is pivoted by means of a pin 66. The lower end of said toggle link is pivotedv to another toggle link 67 and to a link 68by means of a pin '69. The lower end of the toggle link.

67 is pivoted by means of apin 70 to downwardly projecting arms 71; The link 68 is made n two parts joined together by a turnbuckle 72 and is connected at its rear end by a pin 73 to a lever'74 pivoted at 75 to the frame ofthemachine and provided at its upper end witha cam roll 76 which bears against a cam 77 and is held inengagement vil57 and between said anvil therewith by a spring 78. Byrotating the turn-buckle 72 in the proper direction, the

tube 58, with the anvil 57,'c'an be raised or lowered to bring the same nearer to or farther'from the upper surface 63 of the work-support 5-l, a nd also nearer toor farther from the driver 20. Normally the uppersurface Q 63 of" the Worksupport 54: is located above the upper surface of the anand the lower end of the driver 20. s

The rivets used in this embodiment of my invention are tubular rivets and the operation of riveting is illustrated in three steps in Fi 's'. 4, 5 and 6. As hereinbefore set [forth t e rivets descend the raceway '34 andenter a chamber or.pocket 79 located between the carrier blocks 36 and 37.

Thework, consisting of a plurality of plates of, sheet metal 80 and SI which are to be riveted together, is placed upon the worksupport in the position illustrated in Fig. i, with the under surface of the plate 81 resting against the upper surface 63 of the stationary work-support 5%. In this position of the parts it will be seen that "the work engaging surtace of the work-support lies in a plane between the driver 20 andthe work engaging surface of the anvil 57. a

The guide pin 62v at that time projects through two layers of sheet material 80 and 81. I

The tubular rivet 82, held in the pocket 7 9 of'the carrier and between the blocks 36 and 37,is moved downwardly by the lever 46 until the guide pin 62 enters the bore of said tubular rivet, as illustrated in Fig. 4. The driver 20 at the same time is actuated as hereinbefore described by the toggle links and 24 and theactuating moved downwardly by its slide .21 which is 7 link 25, crank-pin 29, cam 30 and shaft '16,

and as said carrier and driver descend the rivet is placed upon the upper end of the guide-pin 62 and is guided by said guidepin through the holes 83 and 84 providedin the plates 80 and 81 and after the rivet is thus positioned the driver QOcontinues to descend, pushing the rivet out from between the carrier blocks 36 and 37 and pushing the guide-pin 62 downwardly against the action of the spring 59 until the parts assume the relative positions illustrated in Fig.5, in which it will be noted that the rivet- 82 has been pushed through the holes 83 and '84 in the plates 80 and 81 and that the under side of the. head of said rivet bears against the upper surface of the plate 80, while the end of the rivetwhiclr is to be clenched projectsthrough the plate 81 a sufficient distance to be formed into a curled over clench by the final step in the riveting operation, the

plates 80 and 81 being clampedtogethen Up to,this point the anvil 57 remains 'stationary. As soon, however, as the rivet is inserted in place and the .plates'are clam ed 7 together by the driver,'as illustrated in ig. a

5, the anvil is moved upwardly and engages the downwardly projecting end of the rivet 82,-whereupon said projecting end will be curled over and rivetedagainst the under surface of the plate 81. This movementof the anvil is accomplished through'the cam 7 7, lever 74, link 68 and togglelinks 65 and 67 and in this operation the projecting lower end of the rivet 82 encounters the anvil 57 and said anvil clenches the rivet as hereinbefore described in a manner well known to those skilled in this art, thus firmly clamping and riveting the plates 80 and 81 together without any tendency to cramp the rivet S2 or to makeit buckle=prior to the clenching operation. a
